Hi,

After configuring build directory for m32r-elf, this
is what I get:

>make -C root/build/opcodes/ stamp-m32r
make: Entering directory 'root/build/opcodes/'
make: no rule to make target '../cgen/stamp-cgen',
needed by 'stamp-m32r'. Stop
make: Leaving directory 'root/build/opcodes/'

If we have a look at stamp-m32r in
src/opcodes/Makefile.in and build/opcodes/Makefile,

stamp-m32r: $(CGENDEPS) $(CPUDIR)/m32r.cpu
$(CPUDIR)/m32r.opc
	$(MAKE) run-cgen arch=m32r prefix=m32r options=opinst
extrafiles=opinst

CGENDEPS = ../cgen/stamp-cgen \
	$(CGENDIR)/desc.scm $(CGENDIR)/desc-cpu.scm \ ...

remain the same for both source and build Makefiles. 
I think this is what might be causing the problem in
build/opcodes/Makefile:

cgendir = $(srcdir)/../cgen
CGENDIR = $(srcdir)/../cgen

Please correct me where I am wrong, doesn't
"cgendir=$(srcdir)/../cgen" mean that cgen source
directory (containing .scm/.cpu files) has to be
present in binutils-2.12 source tree at the same level
as is opcodes directory? I mean to say that as
"binutils-2.12/opcodes" exist, so should
"binutils-2.12/cgen", no? Is this the cause of having
message "No rule to make target ..."?

Regards

Shehryar
